This is a JF-20 compatible type and has the same water purification performance as the genuine product. The double filtration structure of non-woven fabric and activated carbon removes rust and turbidity, and effectively reduces harmful substances such as free residual chlorine, mold odor (2-MIB), and soluble lead. It has been tested to JIS Japanese standards and can be used with confidence for drinking and cooking. The replacement period is approximately 4 months per cartridge (when using 10L per day), and the total filtered water volume is approximately 1,200L. It comes in a pack of 3, making it recommended for bulk replacement. Because it is a compatible product, the shape and specifications may differ from the genuine product. Please be sure to check the compatible water faucet before purchasing.
